IONUNENGINE
See it running
The engine

A game engine written in Rust, with the whole creation suite built in, in a single application.

Mood image

All in one

From asset to playable game, in a single executable.

Sculpt, texture, animate, then launch the game: no export, no import, nothing lost along the way.

Worlds merge

What no separate tool can do.

Paint textures while you sculpt. Lay NURBS over a mesh. Edit the world while the game runs.

Mood image

Rust, end to end

One language, from rendering to editor.

Physics, audio, tools: all of the engine’s code is written in Rust, safe and fast by construction.

The vehicle

Bodywork that deforms. Physics that stays stable.

Physics on jolt-rs, three-level body deformation, physically simulated engine sound.
